摘要
温度性能是影响光纤陀螺性能的主要因素,该文针对光纤陀螺的不同应用环境,对光纤陀螺的结构进行优化设计,通过材料热导率的设计,控制光纤环内的温度变化,从而提高光纤陀螺的温度稳定性;通过ANSYS Workbench的有限元分析法,对陀螺骨架的温度进行模拟仿真,既能对结构设计进行理论指导,又能验证结构设计的效果;最终对组装的高精度光纤陀螺样机进行测试,在未进行任何温度补偿的条件下,零偏稳定性达到了0.001(°)/h量级。
The temperature performance is the main factor affecting the performance of fiber optic gyroscope.The structure of fiber optic gyroscope is optimized according to the different application environments.Through the design of thermal conductivity of materials,the temperature changes in the fiber ring are controlled,so as to improve the temperature stability of the fiber optic gyroscope.By using the finite element analysis method of ANSYS Workbench,the temperature simulation of the skeleton of the gyroscope is carried out,which can not only guide the structure design but also verify the effect of the structure design.Finally,the assembled high-precision fiber optic gyro prototype was tested and the zero bias stability reached 0.001（°）/h without any temperature compensation.
